Using this Stern Defense trigger on a rifle caliber? Want to step down the poundage? By following the included instructions, you can easily swap to their 3 lb green spring for the most solid wall and light break you have ever felt on a two stage trigger.

With pistol caliber AR-15s on the rise in popularity, Stern Defense is leading the way with innovative components to convert your standard AR lower to be compatible with pistol magazines from Glock, S&W, and even Beretta in a variety of calibers. Stern Defense is located in Missouri and dedicated to helping you build the ultimate pistol caliber carbine.

Stern Defense does not recommend the use of our green spring or other light poundage short reset triggers on pistol caliber carbines due to the reciprocating mass. Please use our factory preinstalled spring on the H2S for use with pistol caliber carbines.

BUY IT!

by Henry

How does this not have any reviews? If ur reading this and deciding whether or not you should buy it, BUY IT! This trigger is awesome. I put this in my Foxtrot Mike complete AR9 and it runs amazingly. Rapid fire, slow and steady precision shots, w/e, this trigger performs like a beast. I'm only able to compare it to the single stage nickel boron trigger that came with the FM9. The take-up is short, the break is CRISP, and almost no over travel. And this thing is LIGHT, but the right amount of light for an AR9. I had no bump fire whatsoever. And the shape, I know it's up to individual preference, but I went from a standard AR trigger shape to this beautiful flat/curved shape and I will never go back. Did I mention it comes with anti-walk pins, cause it does. So if ur looking for a new trigger for ur 9mm carbine and ur on the fence on this one, don't be, buy it, buy it now.

Solid Upgrade

by Jeepdudemike -

I have never modified a firearm before. I wanted a better trigger for my Bushmaster QRC AR. I like the feel of a two stage trigger because it reminds me of shooting a polymer pistol (Glock). I took out the stock trigger and easily installed the Stern drop in after reading the directions and watching some YouTube. I shot 40 rounds today and it makes a big difference in the control of the rifle and it is very consistent with pull, break and reset. I did change out the spring after shooting to the green 3lb one to see if I like it better. Seems like a quality product at a great price. I would recommend this to anyone that has an entry level AR looking to make their gun perform better.

A Superb Upgrade

by Matt -

I’m a fan of two-stage triggers, and have Giesselle in my other platforms. However, they claim to not be compatible with AR9 systems and will not warranty their systems for this platform. Which put me on the hunt for a compatible trigger for my Angstsdt UDP-9 stock milspec trigger, which was gritty and heavy. Was a fan of Stern Defense as I had purchased their MAG-AD magwell Glock adapter for AR-15s, and it is of superb quality. The H2S trigger is extremely well made, drop in installation was simple and includes anti-walk pins and alternative lighter spring. Operation is superb; butter smooth and second stage breaks like glass. Highly recommended, and purchase from Primary Arms for always a good value and fast shipping.
